web服务之Tomcat

發(fā)布時(shí)間：2025/3/18 编程问答 20 豆豆

生活随笔收集整理的這篇文章主要介紹了 web服务之Tomcat 小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.

? ??Tomcat 服務(wù)器是一個(gè)免費(fèi)的開放源代碼的Web 應(yīng)用服務(wù)器，屬于輕量級(jí)應(yīng)用服務(wù)器，在中小型系統(tǒng)和并發(fā)訪問用戶不是很多的場(chǎng)合下被普遍使用，是開發(fā)和調(diào)試JSP 程序的首選。

示例 1：Tomcat的配置：

網(wǎng)站規(guī)劃：

網(wǎng)頁(yè)目錄：/web/www ? ?域名：www.test.com

論壇目錄：/web/bbs ? URL：www.test.com/bbs

方案部署：

1 準(zhǔn)備JDK環(huán)境：

[zwj01@localhost local]$ sudo tar -zxf jdk-8u131-linux-x64.gz -C /usr/local/

[zwj01@localhost local]$ sudo ln -s /usr/local/jdk1.8.0_131/ /usr/local/jdk1.8

[zwj01@localhost local]$ sudo vim /etc/profile

export JAVA_HOME=/usr/local/jdk1.8

export PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin

export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tools.jar

[zwj01@localhost local]$ source /etc/profile

[zwj01@localhost local]$ java -version

java version "1.8.0_131"

Java(TM) SE Runtime Environment (build 1.8.0_131-b11)

Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)

2 Tomcat配置：

[zwj01@localhost src]$ sudo wget http://mirror.bit.edu.cn/apache/tomcat/tomcat-8/v8.0.44/bin/apache-tomcat-8.0.44.tar.gz

[zwj01@localhost src]$ sudo tar -zxf apache-tomcat-8.0.44.tar.gz -C /usr/local/

[zwj01@localhost local]$ sudo ln -s /usr/local/apache-tomcat-8.0.44 tomcat8.0

[zwj01@localhost ~]$ sudo useradd tomcat

[zwj01@localhost ~]$ sudo passwd tomcat

[zwj01@localhost ~]$ sudo chown -R tomcat.tomcat /usr/local/tomcat8.0/

[zwj01@localhost tomcat8.0]$ sudo vim /etc/profile

export CATALINA_HOME=/usr/local/tomcat8.0

[zwj01@localhost tomcat8.0]$ source /etc/profile

[zwj01@localhost ~]$ su -l tomcat

[tomcat@localhost ~]$ /usr/local/tomcat8.0/bin/startup.sh?

[tomcat@localhost ~]$ lsof -i :8080

COMMAND ?PID ? USER ? FD ? TYPE DEVICE SIZE/OFF NODE NAME

java ? ?3058 tomcat ? 47u ?IPv6 ?29317 ? ? ?0t0 ?TCP *:webcache (LISTEN)

修改主配置文件（綠色背景為修改后的配置），

[tomcat@localhost tomcat8.0]$ cd /usr/local/tomcat8.0/conf

[tomcat@localhost conf]$ vim server.xml?

<?xml version='1.0' encoding='utf-8'?>

附：

server.xml的配置
server.xml是tomcat的核心配置文件，在tomcat中也需要配置虛擬主機(jī)，server.xml是一個(gè)有標(biāo)簽組成的文本文件，找到默認(rèn)的<Host>標(biāo)簽，在此標(biāo)簽結(jié)尾，也就是</Host>后面增加如下虛擬主機(jī)配置：
<Host name="192.168.60.198" debug="0" appBase="/webdata/www" unpackWARs="true">
??? <Context path="" docBase="" debug="1"/>
</Host>
其中：
?name：指定虛擬主機(jī)名字，這里為了演示方便，用IP代替。
?debug：指定日志輸出級(jí)別
?appBase：存放Web應(yīng)用程序的基本目錄，可以是絕對(duì)路徑或相對(duì)于$CATALINA_HOME的目錄，默認(rèn)是$CATALINA_HOME/webapps。
?unpackWARs：如果為true，則tomcat會(huì)自動(dòng)將WAR文件解壓后運(yùn)行，否則不解壓而直接從WAR文件中運(yùn)行應(yīng)用程序。

?autoDeploy：如果為true，表示Tomcat啟動(dòng)時(shí)會(huì)自動(dòng)發(fā)布appBase目錄下所有的Web應(yīng)用（包括新加入的Web應(yīng)用）
?path：表示此Web應(yīng)用程序的url入口，如為“/jsp”，則請(qǐng)求的URL為http://localhost/jsp/
?docBase：指定此Web應(yīng)用的絕對(duì)或相對(duì)路徑，也可以為WAR文件的路徑。
這樣tomcat的虛擬主機(jī)就創(chuàng)建完成了。
